On July 31, 1994, at 1745 eastern daylight time, a Cessna 210L, N90074, piloted by the registered owner, collided with a vehicle on a roadway during an aborted landing attempt at Dalton's Airport in Flushing, Michigan. The vehicle was destroyed and the airplane sustained substantial damage. The private pilot and one passenger, and the two vehicle occupants reported minor injuries. Visual meteorological conditions prevailed for the flight, no flight plan was filed. The flight operated under 14 CFR Part 91, and originated from Boyne City, Michigan approximately 1640. The pilot reported upon arrival at the destination airport, he entered a left hand traffic pattern for Runway 36 (2,510' X 50', asphalt). He stated his first approach to landing was "...too high and too hot..." and ended in a go-around. The pilot stated the stall warning horn was "buzzing" as the airplane touched down from the second approach. He reported the airplane landed hard and "...became airborne again and floated...decision to go around again was made too late." The pilot stated when he realized he could not stop before the end of the runway, he attempted (unsuccessfully) to ground loop the airplane. He reported when he saw the motor vehicle approaching "...on collision course, [I] applied approximately 1 inch power with yoke in [my] stomach to attempt to jump over..." the vehicle. The airplane became airborne again, struck the vehicle, continued across the roadway and came to rest inverted about 120 feet north of the departure end of the runway. The pilot's statement indicated the winds were reported to be out of 180 degrees at 7 knots at the time of the accident. In the pilot's narrative he stated he checked the wind sock at Dalton's Airport during the go-around after the first approach, and it was "empty."
